I’m developing with EX2100 and DL2100. I create a same app as official demo and run normally in my unbuntu 14.04
but when I install it to DL2100, it always show “Failed to install app” without any failure reason.
I logged in through SSH, checked several places, like “/var/log”, still cloud not find any log file about that issue.
Is there any solution to find the error reason.
